Language doesn't seem to require conscious thought either. Philosophers like Heidegger and Wittgenstein talked about that a lot. The postulating of an internal thought process "behind" everything is basically what Heidegger spent his life refuting, from what I've read of Dreyfus's book... And Wittgenstein explains language as a tool that people use to get things done, more or less. You can talk without "really thinking", people do it all the time. Grammar is natural in that sense. Pinker's "The Language Instinct" mentions studies that show higher educated people in some situations tend to make more grammatical blunders and to be slightly less "fluent," maybe because of second guessing their language instincts. (Any errors in this comment due to the fact that I wrote it without thinking.)
